ComicCon.news can report exclusively that Twin Peaks star Sherilyn Fenn has signed on for a role in the highly anticipated live action Titans TV show, which is being produced for the new DC streaming service. The series is expected to debut next year.

While we don’t know what the specific role is, or whether it is a recurring role or guest spot, we do know that Ms. Fenn is in Toronto currently filming scenes, before flying to Pittsburgh on Friday to appear at the Steel City Con on Saturday. (along with fellow Twin Peaks stars Kimmy Robertson and Harry Goaz, who will be attending the con on all three days.)

This is actually Ms. Fenn’s second role in the DC Universe. In a bit of trivia, she was actually the first actress to ever play Harley Quinn in a live action show, when she portrayed the fan-favorite in the unaired pilot of the short-lived WB series Birds of Prey, which ran for 13 episodes in the 2002 season. When the pilot was picked up and the role was expanded, Ms. Fenn was unable to participate and the role was recast with Mia Sara (from Ferris Bueller’s Day Off fame.)
